Flash messages derive from Rails, and are used to expose messages from one
action to the next, after which they are cleared; a typical use case is with
Post/Redirect/Get, where they are created in the POST handler, and then
displayed by the GET handler to indicate success or failure to the end-user.
This component provides a flash messenger controller plugin for laminas-mvc
versions 3.0 and up.
